Injector cooling arrangement for motor vehicle, has stack of washers placed between cylindrical nozzle and wall of section for permitting conductive transmission by of heat accumulated in nozzle to heat engine element

摘要

#CMT# #/CMT# The arrangement (10) has an axial housing (12) receiving an axial injector (16) with a section (18) receiving a cylindrical body of the injector such that a part of the body is in contact with the section. The injector has a section (22) that receives a cylindrical nozzle (24) with a clearance. A stack (26) of washers (28, 30) is placed between the nozzle and a wall (31) of the section (22) for permitting conductive transmission of heat accumulated in the nozzle to a heat engine element (14) e.g. cylinder head. The stack is formed by alternation of the washers (28, 30). #CMT#USE : #/CMT# Arrangement for cooling an injector in a housing of an element e.g. cylinder head and exhaust line, of a heat engine of a motor vehicle. #CMT#ADVANTAGE : #/CMT# The stack of the washers are arranged for improving the contact between the washers, so that conduction and convection of the heat accumulated in the nozzle of the injector towards the heat engine element is improved, thus improving the cooling of the injector and its nozzle. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a cross-sectional view of an injector cooling arrangement. 10 : Injector cooling arrangement 12 : Axial housing 14 : Heat engine element 16 : Axial injector 18, 22 : Axial injector`s sections 24 : Cylindrical nozzle 26 : Washers stack 28, 30 : Washers 31 : Wall.
